I'm running a 3080 FE and 5800X with a Corsair SF600 Platinum without issue, I was a bit worried but I haven't had any crashes, is it likely to limit performance without enough power?
The EVGA power meter suggests a 750W for your system with 1 SSD and 1 mechanical drive. It’s certainly not under estimating if you are running a 3080 on a SF600.
